Released in 2010, the XO-1.5 laptops were targeted to younger children in developing countries in order to provide them with access to knowledge, experimentation, and exploration of ideas. Designed by the nonprofit organization One Laptop Per Child (OLPC), they claim that the device isn’t a typical laptop but instead a “sub notebook computer"- it utilizes flash memory instead of hard drive. Because this model contains more features than its predecessors [more responsive keyboard, larger flash storage, improved touch pad, faster charge, etc], its starting retail price was set at $300 (previous XO-1 was $199).

A set of three dots on both sides of the hinge cover will identify the XO-1.5 laptop. The original model, the XO-1, doesn't have dots on the hinge cover. The third model, the XO-1.75, has seven dots on the hinge cover.
